Question

Maria plans to rent a boat. The boat rental costs $60

per hour, and she will also have to pay for a water

safety course that costs $10. Maria wants to spend no

more than $230 for the rental and the course. If the

boat rental is available only for a whole number of

hours, what is the maximum number of hours for

which Maria can rent the boat?

Answer 1

Answer: she can rent a boat or 2 hrs and 30 mins

Explanation:

60+10=70

70+60=130

130+60=190

190+30=220

Answer 2

In this question, we're trying to find how many hours Maria can rent the boat for.

We know that the boat rental costs $60 per hour

We also know that she has to pay a one-time fee of $10 for a safety course

Turn this into a equation:

y = 60x + 10

However, she doesn't want to spent no more than $230. Add that to your equation

230 = 60x + 10

Solve the equation to see how many hours she can rent the boat for.

230 = 60x + 10

Subtract 10 from both sides

220 = 60x

Divide both sides by 60

3.67 = x

Since the boat can ONLY be rented by whole hours. With the money Maria has, she can only rent the boat for 3 hours.

Answer:

3 hours
